Problem $03\mathrm{.}081-$ Consider a power transmitting countershaft carrying two Vbelt pulleys

A countershaft carrying two $V-$belt pulleys is shown in the figure. Pulley A receives power from a motor through a belt with the belt tensions shown. The power is transmitted through the shaft and delivered to the belt on pulley $B.$ Assume the belt tension on the loose side at $B$ is $15$ percent of the tension on the tight side. Given: $B(d_B)=4\mathrm{.}00in,T(A_1)=200\mathrm{.}0lb,$ and $T(A_2)=33\mathrm{.}3lb$

Problem $03\mathrm{.}081.$d $-$ At the location of the maximum bending moment, determine the bending stress and torsional shear stress.

At the point of maximum bending moment, determine the bending stress and the torsional shear stress.

The bending stress at the point of maximum bending moment is

psi.

The torsional shear stress at the point of maximum bending moment is

psi.
